2017 Honda Ridgeline. The Honda Ridgeline is a unique pickup that employs car-like unibody construction in place of the rugged but unrefined body-on-frame setup that underpins its competitors. As a result, the Ridgeline provides a more comfortable ride and better handling than most pickups while still offering decent towing and hauling capabilities.
The flatness tolerance references two parallel planes (parallel to the surface that it is called out on) that define a zone where the entire reference surface must lie. Flatness tolerance is always less than the dimensional tolerance associated with it. Tolerance Zone: Two Sets of Parallel Planes where the entire referenced surface must lie. Gauging / Measurement: Flatness is can be measured using a height gauge run across the surface of the part if only the reference feature is held parallel.
Surface Roughness Conversion Chart. Surface roughness ot texture is the measure if the finer surface irregularities in the surface texture and is composed of three components: roughness, waviness and form.These are the result of the manufacturing process employed to create the surface.Surface roughness average (Ra), also know as arithmetric average (AA) is rated as the arithmetic average deviation of the surface valleys and peaks expressed in micro inches or micro meters.ISO standards use the term CLA (Center Line Average).hese are the result of the manufacturing process employed to create the surface. Surface roughness average (Ra), also know as arithmetric average (AA) is rated as the arithmetic average deviation of the surface valleys and peaks expressed in micro inches or micro meters.
